A simple calculator to keep in the chat

What it does

A basic calculator with the four operations, percent, sign change and delete. Keep it in a chat (for example Saved Messages) to have a calculator at hand without installing an extra app. It works offline and shares nothing with the chat.

How to use it

Tap the digits and an operation.
Tap = to see the result.
Use % for percentages and +/- to change the sign.
AC clears everything; the arrow key deletes the last digit.
